Value Collection JY4847117 Hand Tap 3/4-14 Uns Hss

Product Description

The VALUE COLLECTION JY4847117 is a 3/4-14 straight-flute hand tap designed for cutting internal UNS threads in a right-hand direction. Built from high speed steel (HSS) with a bright, uncoated finish, this tap delivers reliable thread-forming performance across a range of machinable materials. It features a plug chamfer with 4 flutes and carries a Class 3B fit designation with an H3 thread limit, making it appropriate for close-tolerance threading work. The overall length is 4.25 inches. This tap is intended for use by machinists, maintenance technicians, and tradespeople performing manual threading operations with a tap wrench or tapping fixture.

This hand tap is suited for shop, field, and maintenance applications where 3/4-14 UNS internal threads are required. The plug chamfer style — typically 3 to 5 chamfered threads — makes it appropriate for through-hole threading or as a follow-up tap after a taper tap in blind-hole applications. It is commonly used in industrial maintenance, mechanical assembly, and repair work where precise thread class and limit control are required.

Key Features

• 3/4-14 UNS thread size and standard for specialized thread form applications
• Plug chamfer profile suitable for through-hole and semi-blind threading
• High speed steel construction for durability across a range of machinable metals
• 4-flute straight flute design aids chip evacuation in manual tapping
• Class 3B fit, H3 thread limit for close-tolerance internal thread requirements
• Bright uncoated finish — no additional coating that could alter thread geometry

Compatibility

Designed as a standard hand tap for use in any manual or fixture-assisted tapping setup requiring a 3/4-14 UNS Class 3B right-hand internal thread.

Installation Notes

This tap is installed by machinists or maintenance technicians using a tap wrench or tapping fixture. Ensure the workpiece is securely clamped and the tap is started square to the hole before applying cutting force. Use an appropriate cutting fluid for the base material to extend tap life and improve thread finish. Inspect the tap for wear or damage before each use — a damaged tap can destroy the workpiece thread or break in the hole.
